OneTask

OneTask is a term used in productivity software to describe a design philosophy and set of tools that prioritize finishing a single task before starting the next. The approach is based on the principle that minimizing context switching can improve focus and reduce cognitive load. In practice, onetask interfaces present one active task at a time and allow the user to complete, archive, or delay it before moving on.

Key features commonly associated with onetask include a distraction-free primary pane that centers on the task title and details, simple navigation to mark tasks as complete or postponed, and optional timers or reminders to support focus sessions. Many implementations also provide a lightweight history or archive to review completed tasks, along with basic prioritization or tagging to help organize different task types without cluttering the main view.

Data models for onetask variants typically store task attributes such as title, description, due date, and status, with states like pending, completed, or postponed. Some versions add lightweight metadata such as priority levels or categories, but the emphasis remains on presenting and resolving one task at a time rather than managing multiple items concurrently.

Origins and usage of onetask vary; the term is used by several apps and guides as a design option or mode within broader task managers. It is often linked to broader productivity methods that favor focus, such as timeboxing or minimalistic interfaces, rather than multi-task workflows. See also: single-tasking, timeboxing, focus mode.
